Production of the first MADAS calculator began in 1913 and it was the first arithmometer style step-drum calculator with the capacity to perform division automatically. The associated ingenious mechanical innovations, which control a series of additions, subtractions and carriage movements to allow fully automatic division simply by continuing to turn the handle, were designed by Erwin Jahz of Zurich.
Two models of this machine were produced - the first with 7 input sliders, 7 counters, and 12 result register windows, and the second, as with this one, with 8 sliders, 9 counters, and 16 result register windows [^For more information see John Wolff's entries at http://home.vicnet.net.au/~wolff/calculators/Egli/Egli.htm#MADAS, Rechnerlexikon at http://www.rechnerlexikon.de/artikel/Madas_1^]
This machine was originally owned by the Tye Furniture store, 100 Bourke St Melbourne, Australia and after the firm had no use for it after the war was kept in safekeeping by a staff member (now deceased) who had used it in the financial work of the store. It is said that companies like Tye held onto such machines until after the war, since it was hard to get newer machinery at that time.[^Private communication with previous owner.^]
A table of serial numbers against dates is provided by Martin Reesse.[^Martin Reese, Hamburg 55 erfolgreiche Jahre: //MADAS-Rechenautomaten aus der Schweiz 1913 - 1968//, http://www.rechnerlexikon.de/files/MADAS--8-2010.pdf, viewed 18 February 2012. ^] This suggests that this particular machine was produced in 1917.
